The invention discloses a drive shaft for a small-turning-radius steering drive axle adapting to a paddy field and a dry field. The drive shaft solves the technical problems that the strength, airtightness and durability of double-linkage drive shafts mentioned in the background technology in an existing market of farm machines all cannot meet the requirements. According to the technical scheme, the drive shaft adapting to the small-turning-radius steering drive axle for the paddy field and dry field comprises an outer half shaft and an inner half shaft which are made of steel in type 42 CrMo, a double-linkage fork made of steel in type 40 Cr, a check ring made of steel in type 08 and a wearproof ring made of steel in type GCr15; and the outer half shaft and the inner half shaft are connected with the two ends of the double-linkage fork through a crossed shaft, the wearproof ring is mounted on the shaft neck position, close to the end where the double-linkage fork is located, of the outer half shaft, and the check ring is mounted on the shaft neck position, close to the end where the double-linkage fork is located, of the outer half shaft, and the wearproof ring is clamped to the check ring. The drive shaft has the beneficial effects of the universality of the paddy field and the dry field, mud resistance, water resistance, sand resistance and low temperature resistance.
Description
technical field [0001] The invention relates to a transmission shaft for a steering drive axle with a small turning radius and adaptable to water and dry fields. Background technique [0002] With the development of the agricultural machinery market, duplex transmission shaft products have also developed from the original single plain environment to various relatively complex and harsh environments such as mountains, paddy fields, and low temperature. Ordinary duplex transmission shafts can no longer meet today's complex working environment and ever-increasing user requirements in terms of strength, sealing, turning radius and durability. Contents of the invention [0003] The technical problem to be solved by the present invention is: the strength, sealing performance and durability of the dual drive shaft in the existing agricultural machinery market mentioned in the background technology cannot meet the technical problems. [0004] In order to solve these problems and ...
